The hidden dangers lurking along our favorite trails aren't always what you'd expect. In this eye-opening episode, Jerry welcomes Monica from the Invasive Species Centre to shed light on two particularly hazardous plants gaining ground across North America: wild parsnip and giant hogweed.
These invasive species might look innocuous—one with yellow flowers resembling Queen Anne's lace, the other a massive plant reaching up to 18 feet tall—but both harbor a sinister secret. Their sap contains chemicals that, when exposed to sunlight on your skin, cause painful burns, blisters, and potential scarring. As Monica explains, you don't even need to break the plant to be affected; simply brushing against it while hiking can transfer enough sap to cause serious reactions.
The conversation traces the fascinating history of these plants, from wild parsnip's journey from valuable food crop to aggressive invader, to giant hogweed's introduction as an ornamental curiosity from the Caucasus Mountains. Monica breaks down exactly what these plants look like, how to identify them, and the crucial steps to take if you suspect exposure—including the immediate soap-and-water wash that might save your skin from painful blistering.
For landowners and outdoor enthusiasts alike, this episode provides valuable insights on safely managing these plants, from proper protective equipment to the optimal timing for control efforts. As these invasive species continue spreading along roadsides, trails, and waterways, understanding their dangers becomes increasingly important for anyone who spends time outdoors.
